- and to transmit. to the car framing the stresses of draft and bufiing..Thes e arms are of especial value in connection with cars having woodenunderframing, and may be applied to either old or new cars.-

The principal object of the invention is to provide a draft arm formedof wrou ht metal, to which is secured a bufling ug adapted to bearagainst the body bolster of the car.

The embodiments of the invention are hereinafter described, andillustrated in the accompanying drawings in which Figure 1 is a detaillongitudinal section of the car frame showing the draft arm inelevation.

Fig. 2 is a plan view of the arm shown in Fig. 1;

Fig. 3 is a detail section on the line 33 of Fig. 1;

Fig. 4 is a view similar to Fig. 1, showing a modified form ofconstruction.

Fig. 5 is a plan view of the arm shown in Fig. 4:; and

Fig. 6 is a detail section on the line 6-6 of Fig. 4:.

One of the center sills of the car is represented at 10 and as being ofwood, and the end sill is shown at 11. The draft arm is of wrought metalpressed into form, and comprises a body portion 12 adapted to bearagainst the inner face of the sill 10 and extend over and beyond thebody bolster 13 of the car. The body portion 12 of the arm is providedalong its upper margin with an instanding stiffening flange 14:, and maybe of less height forward of the bolster than in the portion extendingover and beyond the bolster. Forward of the bolster, however, the bodyportion extends downwardly, as shown at 15. this downward extensionpreferably abutting against the bolster 13 and extending forwardly underthe end sill 11.

' An angle bar 16 is riveted to the outer face of the arm section 15; insuch position that its outstanding leaf bears against the under face ofthe sill 10. From the rear end of the section 15 the body portion 12 isprovided with an outwardly turned flange 17, which engages the lowerface of the sill 10. Bolts, as 18, 19,'are passed vertically through thesill 10 and the angle bar 16 and flange 17,*for securing the arm to thesill.

Draft and bufiing lugs 20, 21,preferably of cast metal, are applied tothe inner face of the arm section 15 and are securely riveted thereto.The .bufling lug 21 extends backwardly to and abuts against the bolster13. .Bufling stresses are transmitted through the lug 21 in part to thedraft arm section 15 but largely directly to the bolster 13,

The construction shown in Figs. 1, 2 and 3 y is applicable to carshaving the present standard sill spacing. In cars in which the sills arespaced a less distance than the present standard, the arm is modified inconstruction as shown in Figs. 4, 5 and 6, to

provide for the use of draft mechanism of standard width. To this endthe depending portion 22 of the arm, forward of the body bolster, isoffset outwardly, there being formed between it and the body portion 12an outstanding shelf 23, which fits against the under face of the sill10 and through which the attaching bolts 18 pass, thus dispensing withthe angle bar 16. When this form of construction is followed the draftand bufiing lugs are located directly below the sill.

In both forms of construction the depending section 15, 22, of the armis flanged outwardly at its lower margin, as shown at 24, 25, for thepurpose of increasing the rigidity of the member. The arm is providedwith a shoulder for abutting against the rearward face of the bolster,and preferably this shoulder is provided by securing to the lower faceof the outstanding flange 17 a plate 26.

The bolster may be of any desired form of construction, as may also bethe draft and buffing lugs, it being important only as toone feature ofthe invention that the bufiing lug be prolonged and have a bearingagainst the bolster. The structure may be otherwise modified as todetail without departing from the scope of the invention.

I claim as my invention- 1. A draft arm formed of wrought metal andhaving a body portion adapted to bear against the inner face of a carcenter sill and to extend from the end sill of the car over and beyondthe car bolster, and being provided with a depending portion extendingbelow the car sill and located forward of the bolster and being ofl'setoutwardly to form a horizontal shelf for engaging the lower face of thesill, the upper margln of the body portion being flanged inwardly andthe lower margin of the depending ortion being flanged outwardly, and abu ng lug secured to the inner face of the depending portion of the armand adapted to bear against the car bolster.

2. A draft arm formed of wrought metal and having a body portion adaptedto bear against the inner face of a car center sill and to extend fromthe end sill of the car over and beyond the car bolster, and beingprovided with a depending portion extending below the car-sillandlocated forward of the bolster and being offset outwardly to form ahorizontal shelf for engaging the ing below the car sill and locatedforward of the bolster and bein offset outwardly to form a horizontalshe f for engaging the lower face of the sill and havlng an instandinflange at its upper margin and an outstan ing flange at its lowermargin.
